Research Data for: Adsorption Study of Basic Yellow Dye Dataset Using Ethiopian Kaolin as an Adsorbent
Description
Kaolin adsorbent expected to adsorb the textile dye molecule. Because clay materials have good surface area for adsorption. Also, clay materials have charged, both positive and negative, surface area. Specially kaolin has a dominant-negative surface charge. As a result, kaolin adsorbent will have a potential capacity to adsorb basic dyes. The operational parameters ( effect of dye concentration, pH, temperature, contact time and adsorbent dosage), as well as modeling ( adsorption isotherm, kinetics, and thermodynamics study) on to raw, calcined and beneficiated kaolin, were investigated. Basic Yellow Dye on to the beneficiated kaolin has recorded as highly removal efficiency at pH of 9, initial dye concentration of 20mg/L, time of 60 min, adsorbent dosage 1g/100mL and temperature of 30℃.

Steps to reproduce
Ethiopian Natural kaolin was collected from. Basic yellow Dye synthetic solution was prepared from Chemical Engineering research grad laboratory, Bhir Dar Institute of Technology, Bahir Dar Ethiopia. Adsorbent kaolin was prepared mechanically as crushed, milled and screened using jaw crusher (BB50), disc mill (Pulvisette 13) and Standard sieves (ISO9001), respectively. The adsorbents were treated thermally (calcination) at 700℃ and wet treatment ( beneficiation) with distilled water so as to study the adsorption capacity of dye in addition to the raw kaolin. To know the maximum wavelength of the dyes, scanning of the solution were detected using UV-Visible spectrophotometer (Lambda 35) and calibration absorption were studied with six concentration points. The removal efficiency of the dye was calculated. The equilibrium state concentration (loading) of adsorbate in the solid phase (qe, mg/g) and concentration (loading) of adsorbate in the solid phase at any time (qt, mg/g) were determined. The dye absorbance values were measured by UV/VIS spectrometer (Lamda 35 Ferkin Elmer) at a maximum wavelength. The adsorbents were characterize using thermogravimeter (SDT Q600). The operation parameters, Effect of concentration, temperature, pH, contact time and adsorbent dosage of the adsorption were studied. Also, the adsorption isotherm model, kinetic modeling and thermodynamics modeling were studied
